commercial form of runway which can be adlusted height, the runwayaccording to the invention. An

Fi 91 a fr nt e v on o h nw y h wn arched base member composed of abottom plate in Fig- 8- 10 and arched rocking base 11 supports a tiltingFig. 10 is a longitudinal section of the same runway 12 made of achannel-shaped piece o!" 55 runway in collapsed position, iron havingflanges 13 through which passes a bolt 14 to secure the runway and basetogether. The arched member 11 has ears 15 to hold the bolt 14 inposition at the top of the arch. This runway may be used with any formof axle rest, such as the one shown in Figs. 1 to 3, and its operationis substantially the same as the first described form of the invention.Fig. 7 shows the runway after the wheel has passed over it and the axlesettled upon the axle rest, the runway being about to be kicked out bycontinued rotation of the wheel.

Figs. 8 to 10 show another form of runway, this one being collapsibleand occupying a very small space when not in use. Upon a base 20 havingup turned flanges 21 are pivoted by means of a bolt 22 a pair of struts23 and a single strut 24. The upper ends of struts 23 are pivoted at 25to the down turned flanges 26 of a runway 2'7. Upon the bottom surfaceof runway 27 are two pockets formed by flanges 28 and 29 i to receivethe upper end of the strut 24. When the strut 24 is in the pocket behindflange 28 the runway is closer to the base than when the strut is behindflange 29. Consequently a wheel will be elevated higher by the runwaywhen the strut 24 is behind flange 29 than when it is behind flange 28.The runway rocks upon the bolt 22 as a wheel travels over the rockingcenter of the runway. The operation of this runway is therefore the sameas those previously described.

When not in use the runway can be folded up into the position shown inFig. 10.

Figures 11, 12 and 13 show an axle rest which is particularly adapted tobe used in connection with the rocking runways described above. Twopairs of legs 30 and 31 are held in spread position at the bottom byangle irons 32 and are secured together at the 'top by plates 33. Thetops of the legs are sufficiently far apart to allow the tongue 34 of aT-bar which forms the axle support to pass between them. The tongue oflegs 30 and 31.

the T bar is slotted at 35 to pass over plates 33. The slots 35 slopeoutward and downward and thereby determine the positions of the pairs ofThe parts of the axle rest can be easily assembled and disassembled andin the latter condition occupy little space. One pair of legs may besomewhat shorter than the other pair to make one end of the axle restslightly lower, thus making it easier for the axle to pass over it.

Various modifications of the invention within the scope ,of thefollowingclaims will occur to those skilled in the art.

Having described my invention,

I claim:-

1. In a vehicle jack, an axle rest, a base member beside said resthaving a broad ground engaging surface, and a runway freely rockablymounted on said base member in such a way that an intermediate portionof said runway is supported above the ground while one end thereofnormally rests upon the ground, whereby a vehicle wheel may be run uponsaid runway, said runway being free to rock as the wheel travels overthe rocking center of said runway and adapted to cause the wheel andaxle to execute a rising and falling motion, the supporting surface ofsaid axle rest being positioned to receive the axle during said fallingmotion.

2. In a vehicle jack, an axle rest, a base member beside said resthaving a broad ground engaging surface, said base member including anelevated fulcrum, and a runway freely rockably mounted on said fulcrumso that it stands normally in an inclined position with one end restingupon the ground, whereby a vehicle wheel may be run upon said runway,said runway being free to rock as the wheeltraveis over said fulcrum andadapted to cause the wheel and axle to execute a rising and fallingmotion, the supporting surface of said axle rest being positioned toreceive the axle during said falling motion.

3. In a vehicle jack, an axle rest, a base member beside said resthaving a broad ground engaging surface, said base member including anarched support having a curved. upper surface, and a runway rockablymounted on said support so that it stands normally in an inclinedposition with one end resting upon the ground, whereby a vehicle wheelmay be run upon said runway, said runway being adapted to rock as thewheel travels over it and to cause the wheel and axle to execute arising and falling motion, the supporting surface of said axle restbeing positioned to receive the axle during said falling motion.

4. In a vehicle Jack, an axle rest, a base member beside said resthaving a broad ground engaging surface, a runway, struts rockablysupporting said runway on said base so that it stands normally in aninclined position with one end resting upon the ground, whereby avehicle wheel may be run upon said runway, said runway being free torock as the wheel travels over the center of rocking of said runway andadapted to cause the wheel and axle to execute a rising and fallingmotion, the supporting surface of said axle rest being positioned toreceive the axle during said falling motion.

5. In a vehicle jack, an axle rest, a base member beside said resthaving a broad ground errgaging surface, a plurality of struts pivotedon said base, a runway mounted on said struts and having spacedadjustable engaging means for connecting said struts therewith atdifferent distances apart, whereby the distance between said base andsaid runway can be\ varied, said struts rockably supporting said runwayon said base so that it stands normally .in an inclined position withone end resting upon the ground, whereby a vehicle wheel may be run uponsaid runway, said runway being adapted to rock as the wheel travels overit and to cause the wheel and axle to execute a rising and fallingmotion, the supporting surface of said axle rest being positioned toreceive the axle during said falling motion. v

6. In a vehicle lack, an axle rest, a base member beside said resthaving a; broad ground engaging surface, a plurality of struts pivotedon said base, a runway connected to the opposite ends of said struts,one of said connections consisting of a plurality of spaced pockets toreceivethe opposite end of one of said struts in different positions onsaid runway, whereby the distance between said base and said runway canbe varied, said struts rockably supporting said runway on said base sothat it stands normally in an inclined position with one end restingupon the ground, whereby a vehicle wheel may be run upon said runway,said runway being adapted to rock as the wheel travels over it and tocause the wheel and axle to execute a rising and falling motion, thesupporting surface of said axle rest being positioned to receive theaxle during said falling motion.

7. In a vehicle Jack, a channel bar forming a said strut means andchannel bar iorming a triangle in their operative position, said strutmeans and base being adjusted to fold into the channel of said channelbar in their inoperative position.
